Chapter 361 Duan Hongxuan came up with another solar cooker, and Director Yang was also jealous
Director Yang was impressed by the comfortable environment of Duan Hongxuan's courtyard, and suddenly discovered the simple hot water bucket that used solar energy made by Duan Hongxuan, and asked curiously.
Everyone followed Director Yang's fingers and looked over, and saw two wing rooms to the west, with two large dark barrels placed on the roof.
Duan Hongxuan looked at it and replied nonchalantly: "Oh, you're talking about the water storage bucket on the roof! That's where I put it specifically to get hot water for bathing!"
"Oh? What does this mean?" Director Yang suddenly felt that there was something famous here and asked curiously.
Duan Hongxuan replied in a relaxed tone: "What can be said about this? Isn't this a very simple matter?
Didn't you notice that the outsides of these two drums are pitch black, so that they can absorb the heat of the sun well? Fill them with water and put them on the roof to expose them to the sun for a day. Warm water will be available at any time!
Especially in summer, the water in the bucket is a bit hot at the end of the day. I take hot baths several times a day in summer!
If you have this thing at home, at least you will have free hot water from April to May until October!"
After everyone heard this and thought about it, they immediately admired Duan Hongxuan! Director Yang looked at Duan Hongxuan with bright eyes: "Hongxuan, what do you think your brain is like? Alas! I really don't accept it.
!
Director Lin, did you see it? As soon as Hongxuan said it, we all understood this truth, but before he said it, no one would have thought of it!"
Director Lin also nodded with emotion: "Yes, director, if this is promoted, how much energy can be saved, and how much convenience can it provide to the lives of ordinary people!"
Director Yang was interested in what Duan Hongxuan said about using solar energy to heat hot water, so he got up to take a look.
Everyone was very curious and followed him to the bathroom.
Entering the washroom, Director Yang sighed and said, "Tsk, tsk! I told you that you know how to enjoy it! Look, this washing place is so well done!
You can take a shower at home. It’s so convenient. You can take a shower anytime you want!
Hongxuan, come and show us your solar hot water!"
Duan Hongxuan stepped forward and turned on the hot water switch. Everyone stretched out their hands to try it. Don't tell me, although it is autumn now, the sun is not bright at all during the day. The water is still warm, much warmer than cold water! p>
Everyone couldn't stop praising it, it was so convenient to have this thing at home, especially in summer, when I sweat every time I move, it would be so comfortable to have such a convenient guy who can take a shower!
Everyone envied Duan Hongxuan's bathroom for a while, and then returned to the grape trellis.
Factory Director Yang took a sip of tea, put down the tea cup and looked at Duan Hongxuan and said: "Hongxuan, I am really dissatisfied with your brain! Tell Uncle Yang, can this thing of yours be promoted? What if this can be promoted?
, but it is a great thing that benefits the country and the people!"
Duan Hongxuan thought for a while and said: "Uncle Yang, this is actually very simple, and a bit too simple. If you really want to talk about promotion, it doesn't matter. After all, it is not very efficient!
If you are really interested in solar energy, I really have some ideas that I can tell you about!"
"Oh? What do you think? Let's take a look!" Director Yang suddenly became interested.
"Uncle Yang, have you ever played with a magnifying glass? Just take a magnifying glass, point it at the sun, and use the focus of the sunlight focused by the magnifying glass to burn paper or ants. Many children have played this!"
Director Yang nodded, "I have never played this, but I have occasionally seen children playing it! What? What else is there to say?"
"Talk? There's too much talk here! Think about it, Uncle Yang, with such a small magnifying glass, the focused sunlight can light up a piece of paper.
If there are more magnifying glasses focused on one point at the same time, how much heat can be generated under sunlight?
What if you don’t use a magnifying glass but use a reflector? Use many concave reflectors to focus their reflected sunlight on one point. If there are enough mirrors and enough focused heat, can you boil a pot of water?
?Can we no longer use coal stoves to boil water at home?
This has much more promotional value than the two buckets on my roof!"
"Hiss!" Director Yang thought for a moment and suddenly felt that this was really going to work. If it was really successful, wouldn't it mean that the steel rolling mill would have a new project?
Thinking of this, Director Yang couldn't sit still, leaned out and looked at Duan Hongxuan and said: "Hongxuan, have you studied this matter? Is there really something going on?"
Duan Hongxuan thought to himself, is there any need for research? There must be a clue! If nothing else, an author named Twelve Meridians wrote a novel about a courtyard, in which the protagonist built a solar water heater.
Something!
"Of course I've done something about it. I've done experiments. A large aluminum pot with two thermos bottles of water can be boiled in less than half an hour in the summer!
If you make the reflective surface bigger, your factory canteen can use it to steam steamed buns!"
Director Yang couldn't sit still now, "Hongxuan, do you have any real objects in your hand?"
Duan Hongxuan shook his head: "No! If you want it, Uncle Yang, I can make one for you!"
As he spoke, Duan Hongxuan looked up at the sky and said: "But Uncle Yang, this season is not suitable, it is best to wait until summer!
In fact, if your steel rolling mill really wants to do this solar energy project, don't rush now. You can wait until next spring to start preparations, and then mass-produce it. Prepare a large amount of products first, and wait until the weather warms up. Uncle Yang, you can
Invite superior leaders to come to the factory for on-site observation. I believe that with the physical display effect, the leaders of the ministries and commissions will definitely support your factory in bringing products to the market as soon as possible!
This product is especially effective in areas with longer lighting hours and less rainfall in the northwest region!
It is less practical for areas in the south with more precipitation, after all, it requires sunny weather!
But in general, this kind of solar water heating device is called a solar cooker. Once solar cookers are popularized, they can indeed save a lot of fuel!
In summer, solar cookers are suitable for promotion. During this season, when others buy them, they can see the results immediately. With word of mouth spreading, the product will not worry about selling at all!"
"Solar stove! Okay! This is a good name!" Director Yang shouted excitedly, but still a little worried, "But Hongxuan, can this solar stove really be used as a stove as you said?" p>
Duan Hongxuan shook his head: "It is impossible for solar cookers to completely replace stoves.
After all, the use of solar cookers has certain limitations. It must be sunny and it must be summer.
For example, it cannot be used on cloudy or rainy or snowy days.
In late autumn, early spring, winter and other times when the temperature is low, even sunny days are of no use!
And even on sunny days in summer, solar cookers are not suitable for certain occasions!
Therefore, it is impossible to completely replace ordinary stoves with solar cookers!
Let me tell you, Uncle Yang, there is no need for the steel rolling mill to produce solar cookers. It is better to hand over this product to the ministry and let the ministry arrange for other factories to produce it!
Steel rolling mills should focus on producing machine tools, there is no need to distract their energy!"
After listening to Duan Hongxuan's words, Factory Director Yang shook his head: "Hongxuan, a factory as big as ours can produce machine tools and solar cookers. Why should we give it to others!"
"This is Duan Hongxuan. You may not know much about our factory. Our steel rolling factory is quite large. There are tens of thousands of employees in the whole factory. Products like the solar cooker you mentioned are completely useless to our factory.
No big deal!" Director Lin reluctantly advised Duan Hongxuan.
Duan Hongxuan looked at the excited Director Yang and Director Lin, and shook his head helplessly: "Uncle Yang, Director Lin, what kind of factory are you? A steel rolling mill!
Your factory is a heavy industry factory, and machine tools are also heavy industry products. The production of your steel rolling mill is acceptable.
But products like solar cookers are completely light industrial products, and to be honest, the most that your factory can produce for solar cookers is a base and a shelf. Among them, the most important reflective mirror part, due to cost considerations, is the most
It’s better to use glass, which is not something your steel rolling mill can produce!
Glass is not only important, but also used in large quantities. Even after the product is sold, it is the glass reflective mirror that is most easily damaged and often needs to be replaced!
So I personally think that the most suitable factory to produce solar cookers is not your steel rolling mill, but a light industrial factory that produces glass products such as mirrors!"
When Director Yang heard that the cooked duck was about to fly, he became anxious and wanted to continue to persuade Duan Hongxuan. Duan Hongxuan raised his hand to stop him: "Uncle Yang, listen to me!
To be honest, solar cookers have no technical content, at most they are just ideas and creativity!
Once you have an idea, any factory can produce it. It is really not worth the time and energy of the steel rolling mill to do it manually!
Moreover, Uncle Yang, you haven’t received approval from the ministry yet for the machine tool!
Don't mess around for a long time. In the end, the ministries and commissions did not allow your factory to produce machine tools. They asked you to hand in the information and let other factories specializing in the production of machine tools produce them. Uncle Yang, can your little arm twist the thighs of the higher-level ministries and commissions? What about the steel rolling mill?
The hard work for a long time was not in vain!
In my opinion, it would be most appropriate to find a way to use solar cookers in exchange for the approval of the ministries and commissions to produce machine tools in the steel rolling mill!
Uncle Yang, what do you think?"
After saying that, Duan Hongxuan looked at Director Yang quietly.
